If electronics and dyno service is selected your motor will be dyno tuned in house at Thompson Motorsports. You are welcome to come and see this(by appointment only). Your motor will be completely broken in and will include the dyno print out when complete.

At Thompson Motorsports, each turn key motor is dyno tested, tuned, and broken in so our customers have to do as little work as possible to get their car driving with nothing to worry about.

Every motor will come with a list of specifications as well as a dyno sheet to show how much power was made.

There will be a one year, unlimited mileage warranty on every motor as long as nothing is altered on the motor from when it left Thompson Motorsports.

If an automatic transmission is being used, a torque converter with a higher stall may be required. We can build a custom converter at an additional cost that will best suit the application.

We guarantee all motors to perform as advertised. It is not Thompson Motorsports responsibility to ensure the motor will fit in any vehicle without any modifications to the vehicle.

Shipping will cover the continental US only.
